GAGE FOR LOOMS.

Application filed November 11, 1912.

To all whom it may concern:

Be it known that I, JAMEs MoMAHoN, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Gages for Looms, of which the following is a specification.

The picking-back of the warp and fabric in a loom following the raveling out of the filling back to a point where the faulty laying-in of filling has occurred is an operation at present accomplished by only the most careful and painstaking adjustment of the means for effecting the picking-back operation, in consequence of which the part of the finished goods aifected usually shows a crosswise streak existing either as too great or too little distance between shots of filling in the vicinity where the renewed filling starts. The reason for this is that the test for the position to which the fell should be brought in picking-back, consisting in adjusting the warp and fabric backward or forward until the fell of the cloth will just be touched by the reed dents upon moving the batten to the beating-up position, is too delicate for the eye to accomplish unaided, there actually existing either a spacing of the fell from the dents or a crowding thereof against the dents which may not be ap parent to the eye at that time but which will develop as a clear blemish in the finished fabric.

The object of this invention is to provide a gage whereby the adjustment of the warp and fabric in the picking-back process may be accomplished with accuracy and facility and which will make unnecessary the moving of the batten to the beating-up position in effecting the adjustment, with the inconvenience, annoyance and delay incident thereto.

In the accompanying drawing, Figure 1 shows in plan the gage attached to a loom and in gaging position; Fig. 2 is a vertical sectional view of the breast-beam and batten of the loom, the gage occupying the idle position; Fig. 3 is a view similar to Fig. 2, the gage being in the gaging position; and, Fig. 4. is a plan view of the gage in gaging position.

a is the batten, b the reed, c the shuttle and (Z the breast-beam of a loom of ordinary character; the warp e and fabric f extend over the batten and breast-beam and are Specification of Letters Patent.

Serial No. 730,538.

provided with the usual instrumentalities for supporting and advancing the same and effecting the picking back thereof as occasion requires.

In brackets 9 attached to the back of the breast-beam is supported a horizontal rod 71-, the same standing in a plane preferably slightly higher than the top of the batten, as shown in Fig. 2, when the latter stands in the beating-up position. On this rod is pivotally supported a carrier member consisting of a plate 2' which has one end thereof penetrated by the rod and which may be swung on the rod as a pivot from pendent relation thereto (Fig. 2) to a substantially horizontal position, and which may further be shifted sidewise, or longitudinally of the rod. Said plate has a longitudinal slot 7'. Fitted to this carrier member is the gaging member is provided with a threaded stud or screw Z and wing-nut m for clamping said member to the carrier member on which it is adjustable to limits afforded by the slot 7' through which extends the screw Z,- preferably the member is has a longitudinal groove m on the under side in which the member 2' rather snugly fits, so that member in is guided rectilineally in adjusting it. The free end of member 76 is preferably widened and its edge or gaging portion a is parallel with the reed and hence with the fell of the cloth. Member 70 may also be a plate and its gaging edge is preferably beveled off on the under side as shown.

\Vhen the loom is running the gage hangs suspended, as shown in 2, out of the way of the batten when the same moves to the beating-up position. \Vhen a fault has occurred in the weaving requiring the raveling out of weft and picking-back preparatory to incorporating fresh filling the gage is raised to the position shown in Figs. 1, 3 and 4 and there held by one hand of the weaver while with the other he 0perates the pick-wheel to bring the warp and fabric back to a position where the gaging portion or edge a of the gage is coincident with the fell of the fabric, a condition which the weaver can determine with perfect ease and accuracy and without the necessity of moving the batten back to bring the reed dents against the fell. Primary adjustment of the device is effected by elevating it and then setting its gage member 70 forward or back on the carrier member the proper distance to bring its gaging portion or edge n where it will properly coincide with the fell of the cloth. Since the gage is capable of lateral adjustment along rod h it may be used with varying widths of fabric.

I do not wish to be limited to the exact construction and arrangement of parts or disposition of the device herein set forth, what I claim being:

1. In a loom, the combination, with a fixed supporting means, a fell-gage carried by said supporting means and having its gaging portion parallel with the fell of the fabric.

2. In a loom, the combination, with suitable supporting means over which extend the warp and fabric, a fell-gage carried by said supporting means and having its gaging portion parallel with the fell of the fabric and being adjustable longitudinally of the warp.

3. In a loom, the combination, with suitable supporting means over which extend the warp and fabric, a fell-gage carried by said supporting means and having its gaging portion parallel with the fell of the fabric and being shiftable transversely of the warp and fabric.

4. In a loom, the combination, with the breast-beam and the batten movable toward and from the breast-beam, a fell-gage pivotally supported between the breast-beam and batten on an axis extending transversely of the warp and fabric and having its gaging portion parallel with the fell of the fabric.

In testimony whereof I afiix my signature in presence of two witnesses.
